AI Technical Summary
Technical Problem
Existing wireless communication methods in 5G Proximity based Service (ProSe) L3 U2N relay systems fail to ensure end-to-end security by not consistently enforcing security policies across Uu and PC5 links.
Method used
A communication method where a relay UE determines the activation status of the UP security policy of the Uu link with the base station and activates the UP security of the PC5 link with the remote UE based on this status, ensuring consistent security policies across both links.
Benefits of technology
This approach ensures end-to-end security of communication between the remote UE and the base station by consistently enforcing security policies across both links, thereby enhancing communication security.

Abstract
A communication method performed by a relay user equipment (UE) includes: determining an activation status of a user plane (UP) security policy of a first link between the relay UE and a base station, and, on the basis of the activation status of the UP security policy of the first link, activating UP security of a second link between the relay UE and a remote UE. Related communication methods by a remote user equipment and a base station are also disclosed.
